Good to know

• Add it on grok.com in a browser; xAI doesn't document adding connectors in Grok's mobile apps.
• Grok Business and Enterprise: an admin adds it first at console.x.ai → Grok Business → Connectors → Add Connector → Other.

If it doesn't work

• The popup closes at once or says Connection failed: check the URL is exactly https://mcp.megamcps.com/mcp, then try again with the “OAuth Credentials Required” values above.
• Sign-in fails with invalid_client? Remove the server from the app and add it again.
